LEWIS AUGUSTUS ASPINIVALL, OF JACKSON, MICHIGAN, ASSIGNOR TO ASPINWALL MANUFACTURING COMPANY, OF JACKSON, MICHIGAN,

A CORPORATION OF MICHIGAN.

LIQUlhD-SPRAYER.

SPECIFICATION forming part of Letters Fatent'No. 701,668, dated June 3, 1902. Application filed September 28,1901. Serialllo- 76,825. (No model.)

To all whom it may concern:

Be it known that I, LEWIS AUGUSTUS As-' PINWALL, a citizen of the United States, re-i siding at Jackson, in the county of Jackson and State of Michigan, have invented an Improvement in Liquid-Sprayers, of which thefollowing is aspecification.

ing rows of growing vines or plants-suchfas potatoes, cotton, and the like-with aliquid solution of poisonous material, such as parisgreen, for the killing of insects that infest" such plants; and my invention relates specially to an improvement upon the device shown and described in Letters Patentgranted. to me July 10, 1900, No. 655,333, and to which patent reference is herein made for a full description of the parts and their operations.

The object of my present invention is to simplify the mechanism, to dispense with the special mixing-chamber, to be, able to spray a plant of larger growth, and to mix materials to be delivered upon the plants by agitation in a liquid-holding barrel.

In carrying out my inventionl employ a swinging dependingpaddle within the liquidholding barrel. Movement is communicated to this paddle from a suitable support and an arm therefrom by an eccentric on the main axle of themachine. This paddle keeps the water and the poisonous material within the barrel in a constant state of agitation, so that if the water dissolves the poisonous material or if the poisonous material is simply held in suspension in the water there is in either case no opportunity for a settling of the material in the bottom of the barrel, the solution instead being of the same'consistency through- Connected to this paddle is a flexible hose with an inverted strainer on the lower end near the free end of the'paddle, and the passes down through the hopper and through the opening in the removable top. The swinging paddle also passes through a sliding plate having an opening therefor and which plate rests upon the removable ..top of the hopper and moves over the surface of the top with the movement of the paddle, this latter device preventing the. splashing out of the liquid contents of the barrel.

In my present device I employ sprayingnozzles and pipes of similar character to those set forth in my aforesaid patent, but place the same higher up on the frame, changing the general arrangement of the parts for this purpose, and I prefer to make the nozzles double and diverging. I

In the drawings, Figure 1 is a plan of the devices forming my invention,-the barrel and the parts connected therewith being omitted for clearness. Fig. 2 is a-vertical section and partial elevation upon the line m '00 of Fig. 1, the pumping mechanism being omitted for clearness. Fig. 3 is an elevationand partial section on the line y y of Fig. 1 looking forward from the rear of the machine. Fig. 4c is an elevation and partial sectionon the line a z of Fig. 1 looking forward. Fig. 5 is a plan, and Fig. 6 a vertical longitudinal section,of the filling-hopper and parts connected therewith; and Fig. 7 is a plan of the rocking support for the paddle.

Parts herein corresponding with parts shown in my aforesaid patent carry the same characters of reference.

The wheels a a, are mounted upon anaxle b, and a frame composed of longitudinalmembers 1, transverse members 2, 3, 4, and 5, and the end pieces 6 and 7 are connected together and to the axle b. The frame composed of these parts serves as a platform for carrying the various parts of the mechanism, and the rear ends of the shaft members 0 o arecon I employ uponnected to this frame. The whiffletree dis also connected to a member of the frame between the shafts, and I prefer to employ a suitable seat somewhere on the machine and a bar from the same to a support upon the frame; but this is not shown, as itis not material to the present case. Brackets 8, secured to members of said frame, support the water-barrel c. This water-barrel e is preferably placed across the machine and has an opening in the upper part, and a filling-hopper n is connected to the barrel at this opening. \Vithin this hopper is a removable top a, that is longitudinally slotted. The top is preferably provided with a flange fitting down into and sitting upon the flange of the hopper, and I provide a sliding plate 0, having a transverse mortise or opening agreeing in length with the width of the opening in the top 11., and a paddle 1) occupies a substantially vertical position in the barrel, the same being provided with a tapering portion and having an upper end with parallel edges. This upper end passes through the opening in the removable top and through the mortise in the sliding plate,and the upper end of the paddle is removably connected to a rocking support h, connected by an axis 18 to a bracket h, secured to the outer surface of the barrel. The rocking support it is made with a vertical edge 17, against which one edge of the paddle bears, the said edge acting to maintain the paddle in a vertical position. This rocking support is shown especially in Figs. 2, 3, and 7, a crank-arm forming part thereof. An arm 1" is pivotally connected to the crank-arm portion of the rocking support it at its upper end, and its lower end is connected to an eccentric m upon the main axle b of the machine, and the rotation of the axle raises and lowers the arm 0*,swinging the rocking support h on its axis 18 and the paddle I) back and forth in the barrel, keeping the liquid contents thereof in a state of continual agitation.

A hose (2 passes through the barrel near the filling-hopper and extends upon one side of the paddle and is secured thereto by straps. (Shownin Figs. 2 and 3.), An inverted strainer 16 is connected to the lower end of the hose 6' and occupies a position within the notched lower end of the paddle, and a pipe 1, secured by a strap to the barrel and at its lower end to the platform 15 of the pump, connects at its upper end to the end of the hose. This pipe 1" passes to the pump f. A pipe f extends from the pump to the air-chamber g, and a pipe g extends from the air-chamber to a T- head 9, and in the length of the pipe 9 there is a cock 12 for regulating the supply of the liquid, and at one end of this pipe g there is a hose attachment 31 and another cock for regulating the supply thereto.

I prefer to employ upon the axle b disks is, spaced apart and connected by studs carrying rollers 13. This operates the bar I and the pump-beam Z, the beam being pivoted to a standard Z and springs m are employed in connection with the operation of the pump and beam.

Flexible branches 10 and 11 extend laterally from the T-head 9. These flexible branches are connected to coupling-heads t' on one end of the pipes 0', and on the other end of these pipes are coupling-heads z".

The spray-nozzles are alike and comprise nozzles 20 and 21, which are preferably employed in pairs connected to flexible pipes 22 23, extending to the coupling-heads t' 11.

Arms 19 are secured to the respective ends of the upper surface of the frame part 5, and these arms have rising portions and they extend to and beyond the swivel-couplings s s,

which couplings receive the pipes oyand the arms 19 and are connected thereto by bolts 25 and are adapted to turn at their meeting faces in relation to one another and are clamped by set-screws 26 27 to the arms and pipes, these devices serving to adjustably fix the relation of the parts, and they are similar to devices shown and described in my aforesaid patent. In connection with these devices I employ rods 32, pivotally connected at their respective ends to the coupling-heads and the spray-nozzles, which rods act to hold I the spray-nozzles in an adjustable relation to the coupling-heads and pipes thereto and to prevent the flexible pipes 22 23 being bent and strained by the weight of the nozzles. In my aforesaid patent these spray-nozzles and pipes are placed below the frame parts and nearer to the ground, and they are connected to parts not employed in the present device. In my present invention these spraying devices are placed above the frame for the purpose of spraying taller vines and plants, and the nozzles are made double to direct two spraying-streams upon each row of vines or plants for more effectually accomplishing the work.

Pedals tfor the feet of the driver or attendant are connected to pivoted shafts 28, secured to the frame of the machine, and cranks 29, extending from these pivoted shafts and rods 30, are connected at one end to the cranks and at the forward ends to the pipes 0', so that the said pipes and the sprayingnozzles connected therewith are under the control of the driver or attendant, who by the operation of said cranks and rods can swing the pipes upon the bolts 25 of the swivelcouplings, so as to change the direction of the spraying-streams for more perfectly spraying the rows of plants or vines.
